Obsidian crashes the game

[AchievedZeus574]

Describe the bug When adding Obsidian (ID 49), the game saves and closes.

To Reproduce Steps to reproduce the behavior:

1. Have a modpack with any amount of mods in it
2. Open the Xray menu
3. Add block ID 49

Expected behavior I was expecting the mod to add it without issue like it had with any other block so far.

Additional context Doubt this was part of the issue, but each time I added it I called it "Obsidian" spelled like tha crash-2022-01-08_16.24.29-client.txt t

Wanted to leave an update: It seems to crash with any vanilla block, but modded blocks are fine. Only happens when adding the block, but not when using the pre added ones.
